Applicable Models: All Reads or writes Measurement data, Memory data, or Normalization Divisor data from the Data Access Map location. For Measurement data, use FDATA or SDATA For Memory data, use FMEM or SMEM. When querying memory, you must first store a trace into memory using CALC:MEAS:MATH:MEMorize. For Normalization Divisor (Receiver Power Cal error term) data, use SDIV. Use FORMat:DATA to change the data type (<REAL,32>, <REAL,64> or <ASCii,0>). Use FORMat:BORDer to change the byte order. Use “NORMal” when transferring a binary block from LabView or VEE. For other programming languages, you may need to "SWAP" the byte order. Equation Editor Notes: When equation editor is active on a trace in a standard S-parameter channel, Calc:Data returns the data from the parameter on the trace that was measured last. For example, for the equation "S22 + S33 + S11”, then S33 is the last measured parameter because it uses source port 3. In applications, if equation editor is active and the original parameter for the trace is not requested anywhere in the channel, then zeros are returned. If the original parameter is being measured within the channel, then data for the original parameter is returned. In general, if an equation contains no measurement parameters, then data for the original parameter is returned. Note: The Calc:Data SCORR command to read/write error terms is Superseded with SENS:CORR:CSET:DATA. SCORR commands do NOT accommodate greater than 12 error terms.
Parameters
<cnum>	Channel number of the measurement (optional).
<mnum>	Measurement number for each measurement.
<char>	FDATA	Formatted measurement data to or from Data Access Map location. Display (access point 2). Note: When querying FDATA, data is received in degrees. When setting phase using FDATA, the command expects the data in radians. Corrected data is returned when correction is ON. Uncorrected data is returned when correction is OFF. Returns TWO numbers per data point for Polar and Smith Chart format. For both formats, the data is the real and imaginary data. To retrieve the resistance and reactance of a trace of data, use the Z-Reflection conversion feature. Returns one number per data point for all other formats. Format of the read data is same as the displayed format.
	SDATA	Complex measurement data. Writes data to Data Access Map location. Raw Measurement (access point 0). Note: Write access is forbidden on the standard channel if factory calibration is on (applies to ENA/PXI/Streamline, not to PNA); to disable factory calibration use SYST:FCOR:CHAN:COUP:STAT OFF command. When writing corrected data, and correction is ON, it will be corrected again, resulting in meaningless data. For unratioed measurements, the magnitude of the complex number is in sqrt(mW). Reads data from Apply Error Terms (access point 1). Returns TWO numbers per data point. Corrected data is returned when correction is ON. Uncorrected data is returned when correction is OFF.
	FMEM	Formatted memory data to or from Data Access Map location. Memory result (access point 4). Returns TWO numbers per data point for Polar and Smith Chart format. Returns one number per data point for all other formats. Format of the read data is same as the displayed format. Returned data reflects the correction level (ON\|OFF) when the data was stored into memory.
	SMEM	Complex memory data to or from Data Access Map location. Memory (access point 3). Returns TWO numbers per data point. Returned data reflects the correction level (ON\|OFF) when the data was stored into memory. Returned data reflects the correction level (ON\|OFF) when the data was stored into memory.

Applicable Models: All (Read-only) Retrieves frequency tone data from the modulation distortion measurement.
Parameters
<cnum>	Channel number of the measurement (optional).
<mnum>	Measurement number for each measurement.
<bufferName>	(string) – Name of the buffer to be read. Note: The following names assume a 2-port VNA.

CALCulate<cnum>:MEASure<mnum>:DATA:RAW:CATalog?

Applicable Models: All (Read-only) Returns the list of raw parameters associated with the measurement <mnum>. These are the raw parameters that are actually used by the error correction; the <mnum> measurement may not strictly depend on all of those. For example, 2 port S-parameters. If the DUT has transmission, then changing raw S11 will modify the corrected S22. If transmission is negligible, S22 is unaffected. The list is returned as strings comma separated. For unratioed parameters, the source port separator is ‘_’ instead of ‘,’ to avoid confusion in tokenization. This command applies to a Standard channel only. Application channels will return an error.
Parameters
<cnum>	Channel number of the measurement (optional).
<mnum>	Measurement number for each measurement.
